Description

Technical Field

[0001] This utility model relates to the field of basalt fiber surface modification technology, specifically to a basalt fiber cloth surface treatment device and a basalt fiber cloth production system. Background Technology

[0002] Basalt fiber cloth is a high-performance fabric woven from basalt fibers, which are formed by rapidly drawing and cooling molten volcanic rock through a platinum-rhodium alloy plate. Generally, the main components of basalt fiber cloth are SiO2 and Al2O3, with small amounts of Fe2O3 / FeO, CaO, MgO, TiO2, Na2O / Ka2O, etc. Basalt fiber cloth possesses excellent properties such as high temperature resistance, corrosion resistance, tensile strength, and high stress resistance. Furthermore, it generates relatively little waste and is biodegradable after disposal, making it a truly green and environmentally friendly material. Therefore, basalt fiber cloth is increasingly used in social development and construction, showing promising applications in aerospace, automotive and shipbuilding, military, construction, textiles, and fire protection. For example, by weaving basalt fiber cloth with other materials, it can be used to make fireproof clothing, which is characterized by good fire and corrosion resistance, low price, and environmental friendliness. Alternatively, basalt fiber cloth can be laid inside buildings to provide fire protection.

[0003] With the development of technology, the performance of fibers formed by rapidly drawing and cooling natural volcanic rock molten fluid through platinum-rhodium alloy plates cannot meet the requirements of some special application scenarios. Therefore, researchers are constantly modifying basalt fiber cloth to improve its interfacial properties so that it can be better combined with other materials to obtain fiber-reinforced composite materials with better performance.

[0004] Current modification methods include acid-base etching and plasma modification, but all have some drawbacks. For example, acid-base etching only corrodes some organic matter on the fiber surface to increase the specific surface area and thus improve the bonding strength of the composite material. However, broken bonds still remain on the corroded fiber surface, affecting the bonding strength. Similarly, while plasma modification can react with the fiber surface through physical and chemical reactions to remove some organic matter and broken bonds, the increase in specific surface area is not significant. Both poor bonding strength and low surface area are detrimental to the composite of basalt fiber cloth with other materials.

[0005] In summary, the effects of acid-base etching modification and plasma modification on improving the bonding strength and specific surface area of ​​basalt fiber cloth are limited. Therefore, this application is hereby submitted. Utility Model Content

[0029] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0030] The following describes in detail the overall structure, working principle, and technical effects of the basalt fiber cloth surface treatment device provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0031] This utility model embodiment provides a basalt fiber cloth surface treatment device, such as Figure 1 As shown, it includes a conveying assembly 200, and a spraying assembly 400, a drying assembly 500 and a surface treatment assembly are arranged sequentially along the forward direction of the conveying assembly 200.

[0032] The surface treatment components include a plasma treatment component 600, a powder application and laser etching component 700, and an ultraviolet ozone treatment component 800.

[0033] The basalt fiber cloth surface treatment device in this embodiment includes a conveying component 200. The conveying component 200 can process the basalt fiber to be treated by passing it through a spraying component 400, a drying component 500, a plasma treatment component 600, a powder spreading and laser etching component 700, and an ultraviolet ozone treatment component 800. The spraying component 400 is preferably a high-pressure spraying component 400, especially when cleaning the surface of the basalt fiber cloth, the high-pressure spraying effect is better.

[0034] Specifically, plasma treatment employs an atmospheric plasma processor, which can form new functional groups on the material surface, increasing the adhesion and wear resistance of composite materials; it can also remove broken chemical bonds on the surface of basalt fibers, improving the composite material's compatibility; and it can react with organic matter on the fiber surface, increasing surface roughness and specific surface area.

[0035] The powder-sprinkling and laser etching assembly 700 first sprinkles powder onto the surface of the basalt fiber to be treated, and then uses a laser etching machine to etch it. The powder-sprinkling structure can be equipped with a powder storage box for storing high-strength nanoparticles or high-strength nanowhiskers, such as silicon carbide, zirconium dioxide, zirconium boride, and calcium sulfate, so that different powders can be selected as needed to sprinkle onto the surface of the basalt fiber to be treated. The sprinkled nanoparticles or whiskers are implanted onto the fiber surface, thereby increasing its specific surface area and roughness, which is beneficial for the composite of basalt fiber with other materials.

[0036] During ultraviolet ozone treatment, the conveying component 200 brings the basalt fiber cloth into the treatment chamber of the ultraviolet ozone component. Ultraviolet ozone treatment can oxidize the surface of the basalt fiber. The oxidation process can introduce hydrophilic functional groups, improve hydrophilicity, and thus enhance the bonding force of the composite material. At the same time, ozone can oxidize the organic matter on the fiber surface, improve roughness, and also form an oxide layer to enhance the corrosion resistance of the fiber.

[0037] The basalt fiber cloth to be treated in this application is processed by a plasma treatment component 600, a powder spreading and laser etching component 700, and an ultraviolet ozone treatment component 800. Compared with existing acid and alkali etching and simple plasma modification, it can more effectively improve the surface roughness and bonding of the basalt fiber cloth, so as to facilitate its composite with other materials.

[0038] In an optional embodiment, the surface treatment assembly includes a plasma treatment assembly 600, a powder application and laser etching assembly 700, and an ultraviolet ozone treatment assembly 800 arranged sequentially along the direction of travel of the conveying assembly 200.

[0039] The basalt fiber cloth undergoes several treatments. First, plasma treatment removes organic matter and broken chemical bonds from the fiber surface. Then, powder is sprinkled onto the fiber, and laser technology is used to implant the powder particles or whiskers onto the fiber, increasing its specific surface area and roughness, while also enhancing its toughness. Finally, ultraviolet ozone treatment oxidizes the surface, removing hydrophobic bonds and forming an oxide layer, thus improving the overall corrosion resistance of the fiber cloth. This results in a fiber cloth with high roughness, corrosion resistance, and good hydrophilicity, offering significant advantages when combined with hydrophilic materials.

[0040] In an optional embodiment, the surface treatment assembly includes a plasma treatment assembly 600, an ultraviolet ozone treatment assembly 800, and a powder application and laser etching assembly 700 arranged sequentially along the direction of travel of the conveying assembly 200.

[0041] The basalt fiber cloth undergoes several treatments. First, plasma treatment removes organic matter and broken chemical bonds from the fiber surface. Then, ultraviolet ozone treatment removes residual contaminants. Next, powder is applied and laser etching is used to implant particles or whiskers from the basalt fiber cloth surface onto the fiber, increasing its specific surface area and roughness, while also enhancing its toughness. Because the ozone treatment precedes the powder application and laser etching, the implanted particles or whiskers are not damaged, resulting in a basalt fiber cloth with a higher surface roughness. Furthermore, both plasma and ozone treatments improve the hydrophilicity of the basalt fiber cloth surface, and combined with the higher surface roughness, this allows the basalt fiber cloth to better bond with materials with excessive surface tension.

[0042] In an optional embodiment, the surface treatment assembly includes an ultraviolet ozone treatment assembly 800, a powder application and laser etching assembly 700, and a plasma treatment assembly 600 arranged sequentially along the direction of travel of the conveying assembly 200.

[0043] The basalt fiber cloth is first treated with ultraviolet ozone to remove surface contaminants and form an oxide layer on its surface. Then, powder is sprinkled and laser is used to implant particles or whiskers on the surface of the basalt fiber cloth onto the fiber, increasing its specific surface area and roughness, while also enhancing its toughness. Subsequently, plasma treatment is carried out to remove broken chemical bonds on the surface and introduce new functional groups, which is more conducive to improving the adhesion of the basalt fiber cloth compared to other combinations.

[0044] In an optional embodiment, the surface treatment assembly includes an ultraviolet ozone treatment assembly 800, a plasma treatment assembly 600, and a powder application and laser etching assembly 700 arranged sequentially along the direction of travel of the conveying assembly 200.

[0045] The basalt fiber cloth is first treated with ultraviolet ozone to remove surface pollutants and oxidize the surface. Then, plasma treatment is used to remove residual pollutants and chemical bonds, increasing its surface area. Subsequently, powder is sprinkled and laser is used to implant particles or whiskers onto the fiber, increasing its specific surface area and roughness, while also enhancing its toughness. Compared with other combinations, this is more conducive to balancing the adhesion and surface roughness of the basalt fiber cloth.

[0046] In an optional embodiment, the drying assembly 500 includes an infrared heater and a blower.

[0047] The blower rotates, causing the airflow to be heated by the infrared heater and then blown onto the surface of the basalt fiber cloth to be dried. In some cases, infrared irradiation can also be used on the surface of the basalt fiber cloth to be dried, while the blower increases the airflow velocity on the surface of the fiber cloth to be dried, thereby improving the drying rate.

[0048] The drying assembly 500 may also include a temperature control device and a temperature monitoring device to monitor the surface temperature of the basalt fiber cloth in real time and increase or decrease the power of the infrared heater based on the feedback temperature.

[0049] In an optional embodiment, the conveying component 200 is provided with a placement rod 100 for placing basalt fiber cloth rolls at one end near the spraying component 400, and a guillotine 300 for cutting the basalt fiber cloth is provided between the placement rod 100 and the spraying component 400.

[0050] Specifically, during the operation of the device, the roll of basalt fiber cloth to be processed can be placed on the placement rod 100. The placement rod 100 can be fixed so that the roll of basalt fiber cloth can be rotated under the drive of the conveying device to release the basalt fiber cloth. At this time, clamps or pressure blocks can be set on the conveying device to fix the front end of the basalt fiber cloth. The fixing points can be removed after processing. The placement rod 100 can also be a rotating shaft, which actively releases the basalt fiber cloth onto the conveyor belt of the conveying device under the drive of the motor.

[0051] When the length of the basalt fiber cloth meets the requirements, it can be cut using a guillotine cutter 300. In some cases, the conveyor belt may loosen after long-term use, causing the height of the upper surface of the conveyor belt to decrease. In this case, a support structure such as a support rod or support plate can be installed below the conveyor belt at a position corresponding to the guillotine cutter 300. The support structure is fixed to the frame of the conveyor belt. In this way, even if the conveyor belt loosens, the height of the conveyor belt above the support structure will not change, allowing the guillotine cutter 300 to rotate to the preset position to cut the basalt fiber cloth. It is not necessary to periodically adjust the rotation angle or pressing height of the guillotine cutter 300 during cutting to ensure the cutting effect of the basalt fiber cloth and avoid excessive pressure from the guillotine cutter 300 that could damage the conveyor belt.

[0052] In an optional embodiment, the high-pressure jetting device is provided with a material inlet, which is connected to at least one of a washing liquid tank, a coating slurry tank, and an etching liquid tank via a conveying pipe.

[0053] Specifically, when the surface of the basalt fiber cloth needs to be cleaned, the material inlet can be connected to a washing solution tank, which can contain water, ethanol, or other organic solvents; when a coating needs to be applied to the surface of the basalt fiber cloth, the material inlet can be connected to a coating slurry tank, for example, to improve the toughness of the basalt fiber cloth, the coating slurry can be epoxy resin; when the surface of the basalt fiber needs to be pretreated, such as by acid or alkali etching, the material inlet can be connected to an etching solution tank, wherein the etching solution can be acid or alkali.

[0054] To avoid cross-contamination between different materials, each hopper can also be equipped with a conveying pipe and a spraying assembly 400.

[0055] In an optional embodiment, the powder spreading and laser etching assembly 700 includes a powder spreading machine and a laser etching machine, wherein the powder spreading machine includes a screen and a high-frequency vibrator that drives the screen to vibrate.

[0056] The powder spreading machine includes a screen and a high-frequency vibrator. When the high-frequency vibrator drives the screen to shake, the powder is spread relatively evenly on the surface of the basalt fiber cloth below the screen.

[0057] To facilitate the even distribution of powder onto the surface of basalt fibers, the mesh size of the sieve should be as small as possible while ensuring that the powder can pass through.

[0058] This utility model also provides a basalt fiber cloth production system, including the basalt fiber cloth described in any of the foregoing embodiments.

[0059] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
